Abstract
Photoelectron spectroscopy is a powerful tool in characterizing the electronic structure of materials. To investigate the specific region of interest with high probing efficiency, in this work we propose a compact insitumicroscope to assist photoelectron spectroscopy. The configuration of long objective distance of 200 mm with two-mirror reflection has been introduced. Large magnification of 5 × to 100 × , lateral resolution of 4.08 μ m, and longitudinal resolution of 4.49 μ m have been achieved. Meanwhile, the testing result shows larger focal depth of this insituoptical microscope. Similar configu-rations could also be applied to other electronic microscopes to improve their probing capability.
期刊介绍：
Chinese Optics Letters (COL) is an international journal aimed at the rapid dissemination of latest, important discoveries and inventions in all branches of optical science and technology. It is considered to be one of the most important journals in optics in China. It is collected by The Optical Society (OSA) Publishing Digital Library and also indexed by Science Citation Index (SCI), Engineering Index (EI), etc.
COL is distinguished by its short review period (~30 days) and publication period (~100 days).
With its debut in January 2003, COL is published monthly by Chinese Laser Press, and distributed by OSA outside of Chinese Mainland.
